ISC2010: Bank Erosion Assessment for Victorian Rivers Using Remote Sensing

A 2010-13 state-wide mapping project in Victoria assessed river bank erosion using 15cm aerial photography and multi-pulse LiDAR data. The Department of Environment and Primary Industries developed this methodology to derive the Bank Condition Metric for the Index of Stream Condition. The resulting data includes vector, raster, and tabular summary statistics designed to join with river centerline feature classes.

Use Cases

• Assessing river bank stability based on the proportion of bank face eroding above expected rates.
• Joining statistical summaries to river centerline geospatial data for integrated analysis.
• Monitoring changes in physical stream form using metrics derived from LiDAR and aerial photography.
• Informing riparian vegetation management strategies based on correlated physical form assessments.

Strengths

• Derived from high-resolution 15cm true color and infrared aerial photography.
• Uses four-return multi-pulse LiDAR data to create digital terrain and vegetation models.
• Part of a systematic, state-wide assessment conducted over a multi-year period (2010-2013).

Limitations

• Column-level documentation is absent; field semantics must be inferred after download.
• Row count is unknown, which may limit suitability assessment.
• Only covers Physical Form and Riparian Vegetation metrics; other Index of Stream Condition metrics are from other sources.
